For superior performance in 3D rendering, machine learning, and engineering, the ASUS ROG Strix G18 stands out with its high-end graphics card and processor. It also offers a larger screen with a higher refresh rate, which is ideal for intensive gaming and multitasking. However, this comes at the cost of portability, as it is heavier and has a larger footprint than the Dell G15 5520. The Dell G15 5520, on the other hand, is more portable and offers better battery life, making it suitable for on-the-go use and general tasks, while costing less. If maximum performance is less critical and value for money is important, the Dell would be the better option. Give Feedback

Although they have very similar scores, PerfectRec considers ASUS ROG Strix G18 to be very good for general use, while the Dell G15 5520 is good.
The ASUS ROG Strix G18 outshines in general use chiefly due to its superior CPU and RAM, providing faster and smoother multitasking, along with better screen quality for vivid visuals, while the Dell G15 5520 holds its ground with a proficient CPU and ample RAM, but its edge in portability and battery life offers an advantage for users on the go. However, the Strix's greater performance and display capabilities imply reduced portability and shorter battery life, compared to the more balanced Dell G15 that trades off some screen quality and raw power for better mobility and longer unplugged usage.

Florian Glaser | March 2023
"With the ROG Strix G18, Asus has made an almost consistently good debut in the still quite new 18-inch laptop segment. The base unit case shows a few signs of weakness in the area of stability and is something which has an effect on the perceived quality of the input devices (the chassis tends to rattle a bit). Nevertheless, thanks to generous port features (incl. Thunderbolt 4), a striking design, and extensive lighting (keyboard, LED strip on the front), gamers get a fitting gaming platform."

"The Dell G15 (2022) is a 15.6-inch budget gaming laptop, and is great for gaming. You can configure the laptop with powerful Intel 12th Gen. CPUs and various NVIDIA dedicated GPUs, all of which deliver a smooth gaming experience at 1080p. There's also a QHD 240Hz display option if you want better visuals, though you'll have to pair it with the top-end NVIDIA GeForce RTX 3070 Ti to get good frame rates. It doesn't get overly hot or loud under load, and there's no noticeable throttling on the CPU or GPU. Unfortunately, the 120Hz panel has a slow response time, causing noticeable ghosting, and it doesn't support variable refresh rate."
